"UNITED STATESv PATENT OFFICE.

I'IOMER M. CALDWELL, OF 'VORCESTER, MASSACHUSETTS, ASSIGNOR TO THEIIARRINGTON & RICHARDSON ARMS COMPANY, OF SAME PLACE.

CARTRIDGE-EJECTOR FOR REVOLVING FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 415,444, -Li ed lovanos- 19, 1889.

Application filed July 18, 1889.

To all whom it may concern:

3e it known that I, HOMER M. CALDWELL, a citizen of the United States,residing at IVorcester, in the county of lVorcester and State ofMassachusetts, have in vented certain new and useful Improvements inRevolving Fire-Arms, of which the following, together with theaccompanying drawings, is a specification sufficiently full, clear, andexact to enable persons skilled in the art to which this inventionappertains to make and use the same.

This invention relates to improvements in shell-ejectors of that classwherein a spider or plate fitted to the rear end of the revolvercylinderand fixed to a central stem is adapted to be forced backward bymechanism arranged to work in connection with thehinging joint for ejecting the cartridge-shells when the barrel is tilted forward, theobject of my present invention being to provide a simple, durable, andefficient means to lock the finger-disk for forcing out theejector-spider, and for automatically' releasing the fingerdisk when thespider has reached a given limit of projection by the tilt-ing of thebarrel; also, to afford a construction that can be manufactured witheconomy and practical facility.

In a former patent, No. 383,701, I have shown and described an ejectormechanism in which I employ an intercepting-stud of somewhat similarnature to that herein shown, but having only a single notch, and inwhich the finger-disk is provided with a reciprocating bolt for engagingsaid stud; but my present invention is an improvement thereon whichaffords a different and simpler construction with less parts and withless parts which are movable, thus making a more desirable andeconomical mechanism for the purpose.

In the drawings, Figure l is a part side, part sectional, view showingmy improved ejector mechanism, the barrel of the arm being in normalposition. Fig. 2 is aview showing the same with the barrel tiltedforward to a position immediately preceding that at which thefinger-disk is released. Fig. 3 shows in side and edge detail views theform of the finger-disk. Fig. et is a top plan view Serial No. 317,885.(No model.)

of the fore end of the frame with the barrelhinge removed. Fig. 5 showsthe side and bottom of the barrel-hinging ears. Fig. 6 is a side viewofthe fore end of the frame. Figs. 7 and 8 are enlarged sectional diagramsillustrating the arrangement and action of the intercepting-stud.

In referring to parts, A denotes the frame; B, the barrel hinged to thefore end of said frame by the pivot-pin d to swing downward,

as indicated in Fig. 2, and locked to the upper'part of the frame by thelatch b when in normal position, as in Fig. 1. @indicates the cylinder,and D the ejector spider or plate fitted into the end of the cylinderand fixed on a stem D', that extends through and is longitudinallymovable in the cylinder-supporting quill E, and is furnished with aspring d, all of which parts can be of suitable or wellknownconstruction for ejecting the cartridgeshells from the cylinder-chambersin the usual manner.

The finger-disk F is, as shown in Fig. 3, a plain flat disk of uniformthickness, having a central opening o. to fit the hinging-pin a, andprovided with the usual finger f forl engaging the ejector-stem D. Onthe periphery of said disk I provide a projecting lug or detent m,formed and located in relation to the finger f, substantially as shown.The forward edge of the lug m is beveled off laterally, as at m. Saidlugis best made integral with the disk F, or,.if otherwise attached, soas to be rigidly fixed on the periphery of the disk. The finger-disk Foccupies position between the ears B, and is free to move with theaction of the spring d, except when its lug m is intercepted, ashereinafter specified.

The fore end of the frame has two plain circular hinging-ears A withtransverse central openings for the pivot-bolt a, and a recess r isformed between them, as shown. The hinge of the barrel B has twocircular ears B', one of which is plain, while the other is providedwith a stationary projecting lug or detent t, disposed on its peripheryat the position indicated, and so that it will pass into the recess r inthe fore end of the frame when the barrel is tilted forward, a notch nbeing provided for its passage. The rear edge of the lug 15 is beveledoff, as at t. The

IOO

lug t can be rnily inserted inl the hinge-ear B or formed integraltherewith, so that it serves as a rigid part on the ear.

I indicates the intercepting-'stud or slidebolt, arranged in alaterally-disposed openving in the fore end of the frame'A, where it isconfined to have a proper limit of endwise movement-by a screw J, thehead of which engages a notch j on the side of said studas shown. Theupper side of the stud extends into the recess or cavity r adjacent tothe hinge-ears. A spring L in the bottom of the cavity serves to pressthe stud I outward and v ing the finger f to throw up the ejector, as

shown in Fig. 2. When the parts are at position shown in Fig. 2, the lugt and the lug WL are at corresponding positions; hence the lug t doesnot appear on Fig. 2 of the drawings. When the lug t reaches theposition'of the stud Ithe narrow edge of the lug enters the groove ornotch t' and its beveled side t -forces the stud I inward in oppositionto the Spring L as the tilting actionv continues, sliding the stud Iuntil the groove or notch @c is brought coincident with the lug m. (SeeFig. 8.) Then the lug m escapes through the notch and the disk F, beingreleased, allows the ejector to be thrown down by its recoil-spring CZ,the fingerdiskF turning to the position indicated by dotted lines onFig. 2. When the barrel and cylinder are again swung back to normalposition, the projecting lug m, by reason of its bevel m', passesthrough the groove the stud being moved by the inclined surface m topermit its free passage. The disk and ejector can at any time bereleased by pressing the thumb on the outer end of the stud I.

It will be observed that this construction is very Asimple and containsfew loose or sep arable parts.

What I claim as my invention, to be herein secured by Letters Patent,is-

1. The finger-disk having the rigid projecting lug m on its periphery,the barrel-hinge ear having the laterally-beveled projection t thereon,and a spring-'pressedl sliding stud supported in 4the frame adjacent tothe periphery of said finger-disk and having two notches z' and :cformed in its side, one of which notches is disposed for engagement withthe projection t for moving the stud when the barrel is tilted, whiletheother notch is disposed to permit the passage of the lug m vthroughit when the stud is forced inward, in

combination with the frame, barrel, hingingpivot, cylinder, ejector, andej ector-spring, alll substantially as set forth.

2. The finger-disk F, carrying the curved finger f and having theprojecting laterallybeveled lug fm. rigid on the periphery thereof,

in combination with the ejector-stem D and spring d, the hinging-pivota, the intercepting-studl I, longitudinally movable in the frameadjacent to the'edge of said disk and having a notch th'rough'which saidlug can pass, a spring L for normally retaining said stud with its notchout of line with the disk,

and means for moving said stud, with its notch, in opposition to thespring-pressure, and bringing said notch into line with said disk,substantially as set forth.

3. The combination of theframe provided at its fore end withhinging-ears and a recess r between the same, the barrelwithhinging-ears B', one of which has a beveled projection on its periphery,the lejector having a stem that extends-through thecylinder-axis, withitsl end above the hinge, the linger-disk carrying a linger f, thatengages Vthe ejectorstem, and provided with a lug that projects downwardfrom its periphery into the recess r, the axis or hinging-pin,'thedual-'notched intercepting stud v"supported in the frame, with its endprotruding at the side thereof, thestud-retaining screw J, and thespring L, beneath the inner end of the stud, all arranged and organizedfor operation substantially as and for the purpose set forth.

'Witness my hand this 16th day of July, A. D. 1889.
